MITSUKI TAROU

Mitsuki Tarou is the music teacher at the school that the 3 mermaid princesses go to. He is a very talented musician who specializes
in not only playing the piano (he mostly plays music by Kaito's father), but composing music as well. He goes to piano recitals
all the time to perform his signature piece ^^;
Like Kaito, he had an encounter with a mermaid before, while taking a stride along the Indian Ocean coastline. The mermaid
had long, beautiful curly hair. Ever since he saw the mermaid, he is unable to forget about her.
We find out the mermaid turns out to be the Sara, the orange mermaid princess. They had a romantic relationship that lasted
not too long, because Tarou had to return home. Sara thought he had abandoned her, but it's not the case at all...he constantly
thinks about her, and even composed a piano piece named "Mizuiro no Melody" dedicated to her.
Later on he was lured by Sara to enter Gaito's castle, where Sara hypnotized him into playing "Mizurio no Melody" endlessly.
He feels very guilty to see the evil Sara when he woke up, assuming it's his fault for leaving Sara so depressed.
